Way back in 1988, I had a contract with the Post and Telegraph Department of Thailand, which lasted more than three months. During that time, I bought a big black grammar book called “Fundamentals of Thai Grammar”. Although I found the phonetics (transliteration) system obtuse, the book is a wonderful resource of everything you ever wanted to know about Thai grammar. Indeed, every time I pick up the book to look up something, I invariably get distracted by all the other useful little tidbits. There are hundreds, if not thousands, of little nuggets of information as to why you would use this word as opposed to that word.
This book is available in ebook HTML format, ready to download. It costs only $9 and is available from here.
This is the same grammar book that is included free in Speak Easy Thai.
